Another week, another enormous tranche of new women’s tennis data on Tennis Abstract. Today I present an extensive view of the 1963 season, including about 250 events and almost 3,000 matches. The season page is here, so jump in whenever you’d like.
This is the fifth amateur-era season I’ve added. I hesitate to use the word “complete,” because there is no clear line separating “tour level” from the rest, and for many of the tournaments I have only partial results. Even for the top players, some early-round matches may be lost to history. But as an in-depth view of the era, we continue to break new ground. For comparison, there were about 3,100 WTA tour-level matches in 2019, and we now have almost the same number of results from 1963.
I’ve made a few more improvements to the season pages, which are now available from 1963 to 1986:
- The Elo rankings table now includes columns for “iElo” — ratings specific to carpet (and wood and tiles and whatever artificial surfaces that organizers put on the floor of their indoor facilities). The “i” stands for “indoor,” although iElo does not include indoor hard or clay results. Those were rare at the time, and are included with the hard- and clay-specific ratings.
- The list of number-one ranked players now shows how long each woman held the top spot–including in other seasons. For 1963, the “list” is rather boring, as it consists solely of Margaret Court, but it does show that Court owned the number one position from the end of 1961 through to her first layoff in 1967. The exact numbers and start/end dates are very much subject to change as I add more data, correct errors, and improve the Elo algorithm, but all told, I have Court at #1 for a total of 536 weeks.
Coincidentally, I recently charted the 1963 Wimbledon final between Court and Billie Jean King. While it was their only meeting this season, it was one of more than 30 in their careers between 1962 and 1973.
As usual, the raw data is now available in my GitHub repo, and I gratefully acknowledge the work done by the Blast From the Past contributors at tennisforum.com.
